FREMONT — One can typically find prostitution activities in red light districts across the country.

But on Thursday it was a busted red tail light on a green 1995 Lincoln Mark VIII that led to the arrest of an alleged pimp.

A 27-year-old San Francisco man was taken into custody on suspicion of pimping, and a 25-year-old passenger was arrested on a drug warrant Thursday after police pulled over a car driven by an admitted prostitute, Detective Bill Veteran said.

The woman was not arrested, but police used their in-car computers to confirm that she was a hooker — they found her ads on Craigslist — and said she received text messages from potential clients during the car stop, Veteran said.

Officers in Centerville stopped the car on Fremont Boulevard near Abbey Terrace because it had a broken tail light and one of the passengers was not wearing a seat belt, Veteran said.

When police questioned the driver, a 21-year-old woman from Moraga dressed in “tiny” shorts and high heels, she told them her pimp was in the front passenger seat.

Police arrested him when they learned he was on parole for a separate pimping case, and then took custody of another passenger who was wanted in a unrelated drug case, Veteran said.
